Louisville, KY – The University of Louisville has released findings
of a study that shows Louisville's air contains an
unsafe chemical. The study shows the concentration
of butadiene has been increasing at a rate of about
35 percent per year since June of 2000.
The chemical was identified last year as the top
toxic air health threat for the Louisville area. The
chemical can cause cancer in humans. It is found
in motor vehicle emissions and its used in the
manufacture of synthetic rubber.
Four years ago monitors detected levels of the
chemical that greatly exceeded what environmental
regulators consider to be safe.
